THOMAS VAUGHAN, ,OF BOSTON, MASSACHUSETTS.

IMPROVEMENT IN BENCH-PLANES.

Specification forming part of Letters VPatent No. 129,695, dated July23, 1872.

Specification describing certain Improvements in Bench-Planes, inventedby THOMAS VAUGHAN, of Boston, in the county of Suffolk and State ofMassachusetts.

My invention relates to a metallic shoe, into which the Wooden body ofthe plane is fitted and secured by means of cement, said shoe beingstrengthened by ribs before and behind y the cutter, and having groovesor lutings cut in various places upon its inner sides to hold the.cement.

In the accompanying drawing, Figure 1 is a plan of the shoe, showing itsshape, te. Fig. 2 is a longitudinal section of the same,

'the shape and position of theplane being shown by dotted lines.

Similar letters of reference indicate corresponding parts; a is thebottom of the shoe. a a are the b is the rib in front of the the openingfor thecutter. e e e are flutin gs or grooves in the sides a a.

This shoe is made of malleable cast-iron, and the body of the plane isout away so as to fit into the shoe. The plane is secured therein bymeans of prepared cement, the flutings e e being for the purpose of morethoroughly fastening it, the cement filling into them. The

. ribs b lc are intended to strengthen the shoe,

and are very important, as it would without them be very liable to breakwhen meeting with a fall from a considerable height. The

y casting throughout is of 'uniform thickness,

(probably one-eighth of an inch,) which gives planes now in the marketand purporting to do similar Work. The Wear is, of course, un-

limited. The general shape of my-shoe may Y be altered, of course, totit different planes, such as block-planes; but the other features ofthe invention will be substantially unaltered..

I do not claim as my invention an iron or entirely metallic plane, butmy shoe, in which is set a Wooden plane, constructed as above described?Having thus fully described my invention, What I claim, and desire tosecure by Letters Patent, ii-

The combination and arrangement of the shoe and sides and ends thereof aa, ribs b c, and lutings e e, substantially as above described, vand forthe purposes hereinbefore set THOMAS VAUGHAN. VWitnesses:
